Abstract

Il est décrit une disposition de cylindre de piston destiné à un compresseur d'air comprenant un cylindre, une bielle ayant une extrémité de réception daxe de piston, un axe de piston fourni dans lextrémité de réception daxe de piston de la bielle, et un piston étant fourni sur la bielle au moyen de laxe de piston et étant positionné à lintérieur du cylindre. Au moins un passage peut être défini dans laxe de piston afin de permettre à de lair de circuler dans laxe de piston à partir du cylindre.
